Giant Danios

The Giant Danio is a very active, colorful species that is native to India, Nepal, and Indochina. At an adult size of around 3 inches (7 – 8 cm), this peaceful schooling fish is an excellent addition to the well-decorated community aquarium and a true giant species for a danio. It is tolerant of a wide variety of water parameters, so it is compatible with virtually all peaceful fish and invertebrates!

Like many typical danios, the Giant Danio is very active and should be kept in schools of at least 6-10 specimens, although even larger schools are more optimal. This fish is very hardy and undemanding in a well-maintained aquarium, but it needs a fair amount of space due to its active and somewhat nervous nature. Stress and nervousness are minimal when this fish is kept in a larger school. The Giant Danio is completely peaceful and rather social with many other fish species as well. It is compatible with almost any small and medium, active, peaceful and semi-aggressive fish and will sometimes appear to school and interact with other species regularly. It will thrive in a planted aquarium with a good amount of decor such as rockwork and driftwood and its color will be most vibrant over dark substrate. It will not bother ornamental plants. It is compatible with any peaceful invertebrates that are too large to be considered prey, but it may prey on small shrimp. This fish is a prodigious swimmer and jumper, so a tight-fitting lid or significantly lowered waterline is necessary to prevent startled or excited specimens from jumping out of the aquarium.
